Title: Apparatus for pipes inner surface cleansing
Inventor: DOLMATOV NIKOLAJ P
IPC: B08B9/053
Filed: 1994-05-10
Granted: 1997-06-20
Abstract: FIELD: pipes cleansing. SUBSTANCE: apparatus operates in the following way: water delivering hose 1 with hydraulic headpiece 2 is introduced in cleansed pipe. Water through water delivering hose 1 goes into chamber 6 of body 4 of reactive headpiece 3, in which due to diffuser 5 water flow gradual decrease of speed and pressure increase take place. Presence of step 7 at outlet of chamber 6 increases resistance to flow creating additional pressure in chamber 6 of headpiece 3. In the case, pressure increase in chamber 6 causes increase of speed of stream outflow from holes and its action on pipe walls. Headpiece 3 is put into operation by movable ring 9 shifting to the left being fixed by spring-loaded fixer 10 and by opening of outlet holes 8. Water, outgoing from holes 8, creates reactive force, that provides motion of hose 1 with headpieces inside cleansing drain. With hose moving in resistant forces are increasing, that are overcome by introduction in cleansing pipe of next headpiece 3, spaces between which are determined by calculation. EFFECT: improved process. 2 dwg

Abstract: FIELD: heat-power engineering; generation of superheated steam at preset pressure. SUBSTANCE: superheated steam is generated through throttling followed by heating the saturated steam; saturated steam is produced in reservoir by heating the liquid contained in it at constant saturation pressure which is lesser than pressure at critical point and equal to pressure before throttling; heating the throttled steam is effected through recuperative heat exchange by the same liquid in the same reservoir. During operation of device, liquid flows to housing 1 via branch pipe 7 where it is heated by means of heater 2. Heating is effected at constant pressure. Saturated steam thus formed rises to upper portion of housing 1 and flows to throttle 3. Throttled steam flows to heat exchanger 5 via main 4. Heat exchanger 5 is submerged in liquid being heater in housing. At heat exchange of throttled steam with liquid steam is superheated and flows to consumer through main 6.
